LOUIS LEMKU'HL, OF BALTIMORE, MARYLAND.

ADJUSTABLE SHADE-HANGER.

Specification of Letters Patent.

Patented Feb. 1'7, 1914.

Application filed April 24, 1913. Serial No. 763,359.

To all whom it may concern Be it known that I, LoUIs LEMKUHL, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Adjustable Shade-Hangers: and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to shades, and more especially to the vertically adjustable hangers for carrying the same; and the ob ject of the invention is to produce a hanger of this character having its upper section hinged so that the shade roller may be thrown forward or inward out of the window frame when desired. Further objects will appear from the following specification, and the invent-ion is illustrated in the ac companying drawings wherein Figure l is a front elevation of this device applied to a window; Fig. 2 is a section on the line 23 of Fig. 1; and Fig. 3 is a similar section with the upper section of the hanger tipped forward or inward. Fig. 4 is an enlarged front elevation of the lower portion of the hanger, one end being in central vertical section; and Fig. 5 is a similar view of the left end of the device shown in Fig. 4, with the parts in a different position. Fig. 6 is a horizontal section on the line 66 of Fig. 4. Fig. 7 is an enlarged detail, giving an elevation of one of the side rails of the frame; and Figs. 8 and 9 are sectional views on the line 89 of Fig. 7 showing the parts in slightly difierent positions. Figs. 10 and 11 are still further enlarged-sections on the lines 1010 and 1111 respectively of Fig. 7.

In the drawings is shown a window frame 1V, and an ordinary shade S mounted on a spring roller R which is ournaled in brackets Bthese brackets being fixed in a frame which moves up and down in the window frame and forms a part of the present invention. Said frame comprises two upright side bars 1 rigidly connected near but not quite at their lower ends by a lower cross rail 2, and the upper sections or portions 3 of said side bars are rigidly connected at their upper extremities by an upper cross rail 4: and carry the brackets B just beneath this rail. The entire frame is movable vertically within the window frame W, and the sides of the latter carry rack bars 5 whose inner edges are provided as shown with ratchet teeth while their bodies form dove tailed ribs engaged by upright grooves 6 in the outer edges of the lower portions of the side bars 1. Said rack bars may extend down to the window sill, but at their upper ends they terminate at points 7 which are short of the window'cap by a distance equal to the length of the upper portions 3 of the side bars, for a purpose yet to appear. Each side bar 1 near its lower end is recessed at 8, and pivoted at 9 in the recess is an L- shaped dog 10 having a beveled head 11 at its upper end adapted to engage the ratchet teeth, while its horizontal arm is thrown normally upward by a spring 12. A movable rail 13 extends across the frame just above the lower rail 2 and its extremities project into the recesses S and over the inner ends of said dogs, its own ends being provided with upright slots 14 engaging pins 15 so that it may not become displaced. When the operator grasps the rails 13 and 2 in his hand and presses them together he depresses the movable rail with respect to the lower rail and the entire frame and the ends of the former trip the dog so that their heads 11 disengage the rack bars and the entire frame can be raised or lowered in fact this frame can be raised by passing the hand under the lower rail and lifting on it, although this follows only from making the teeth in the rack bars ratchet shaped and the heads 11- of the dog beveled on their upper sides as shown, and to this construction I do notwish to be strictly limited. With a structure as thus far described, it is obvious that the entire frame and with it the shade roller and shade may be adjusted vertically within the window frame as desired. V

A feature of my invention consists in hinging the upper portions 3 of the side bars to the lower portions 1 thereof so that the upper portion of the frame can be iio and size adapting it to fit said socket 20 when the parts stand in alinem'ent as seen in Fig. 8, and through this tenon is an up right slot 25 movable on the pin 22. The shoulder at the rear of said tongue is provided with a notch 26 which is dove-tailed in cross section and which at this time engages the dove-tail tongue 21. Finally, the lower end of the tenon is beveled as shown at 27. Ordinarily the parts stand as seen in Figs. 7 and 8, and the upper portions 3 of the frame bars are reciprocated with the lower portion. Nhen, however, the frame is pushed upward to its limit so that the hinges between the upper and lower portions of its side bars come opposite to or above the points 7 where the rack bars terminate, it is possible for the operator to grasp the upper cross rail 4, lift the entire upper portion of the frame until the tenons 2 L slide upward within the sockets 20 and the slots 25 slide upward on the pins 22, and then bear this upper portion of the frame forward to the position shown in Figs. 3 and 9 so that the beveled lower end 27 of each tongue strikes the rear wall of the socket 20 and the shade roller R is carried forward out of its usual position. This adaptability of my device is useful where it is desired to admit air to the room above the shade, and yet not admit too much light or any sunlight at this point. In any and all positions of this hanger it is possible to raise and lower the shade S as usual, but when the upper portion of the frame is set inward as shown in Fig. 3 I would preferably pass the shade behind the lower rails 2 and 13 thereof which carry it inward toward the window sashes.

The parts of this device are of any preferred materials, and I do not wish to be limited to details except as set forth in the following claims:

\Vhat is claimed as new is:

1. An adjustable shade hanger made in two sections hingedly connected with each other, and means for adjustably supporting the lower section in a window frame; combined with means for setting the upper section at an angle to the lower section, for the purpose set forth.

2. An adjustable shade hanger made in two sections hingedly connected with each other, and means for guiding and supporting the lower section in a window frame; combined with means for setting the upper section at a slight angle to the lower section when the latter is raised.

3. In an adjustable shade hanger, the combination with the window frame having upright rack bars in its inner faces; of a frame whose side bars are grooved to engage said rack bars, a shade roller mounted in the upper portion of said frame, spring-actuated dogs movably engaging said rack bars, and a movable rail adjacent the lower cross rail of the frame and having its extremities engaging said dogs, for the purpose set forth.

4. In an adjustable shade hanger, the combination with the window frame having upright ratchet bars in its inner faces extending to points near its upper end; of a frame whereof the lower portions of its side bars are grooved to slidably engage said ratchet bars and the upper portions thereof are hingedly connected with said lower portions, the latter having recesses near their lower ends, an Lshaped dog pivoted at its angle in each recess and having a head adapted to engage a rack bar and beveled on its upper side, a spring normally raising the horizontal arm of said dog and throwing the head into engagement with the teeth of the ratchet bar, a movable rail extending across the lower portion of the frame and its ends passing into said recesses and lying over the horizontal arms of said dogs, this rail having upright slots within said recesses, and pins through the recesses loosely engaging said slots, the whole constructed for operation substantially as decribed.
